define Package/node/description
  Node.js® is a JavaScript runtime built on Chrome's V8 JavaScript engine. Node.js uses
  an event-driven, non-blocking I/O model that makes it lightweight and efficient. Node.js'
   package ecosystem, npm, is the largest ecosystem of open source libraries in the world.

  *** The following preparations must be made on the host side. ***
      1. gcc 10.1 or higher is required.
      2. To build a 32-bit target, gcc-multilib, g++-multilib are required.
      3. Requires libatomic package. (If necessary, install the 32-bit library at the same time.)
     ex) sudo apt-get install gcc-multilib g++-multilib
